George discusses his latest effort - fighting off 20,000 separate Denial of Service attacks upon a domain. What is a DOS attack? Can it happen to anyone? Matt explains what these things called 'botnets' are - unsecured home computers remotely controlled by evil spam masters, enslaved to send spam and malicious spyware to other computers.

Both gents discuss how one can clean out a printer - holding your printer over a steaming kettle might not be the best idea - and the perils of cleaning it out, given the design and construction of modern day printers.

Talkback: Matt and George talk out the problems sent in by listeners, including problems with laptop connections, adding another computer user to your ISDN connection, problems with a multistation printer, and how baby monitors tend to knock out wireless internet connections!
